* Rename `playXXX` => `passXXX` why: Better purpose match * Code massage, log message updates * Moved `ticker.nim` to `misc` folder to be used the same by full and snap sync why: Simplifies maintenance * Move `worker/pivot*` => `worker/pass/pass_snap/*` why: better for maintenance * Moved helper source file => `pass/pass_snap/helper` * Renamed ComError => GetError, `worker/com/` => `worker/get/` * Keep ticker enable flag in worker descriptor why: This allows to pass this flag with the descriptor and not an extra function argument when calling the setup function. * Extracted setup/release code from `worker.nim` => `pass/pass_init.nim`
